Description
Technical field
The present invention relates to Wood plastic boards technical fields, and in particular to a kind of environment-friendly, high-intensity faint scent Wood-plastic material and its preparation side
Method.
Background technology
Wood-plastic material, mainly using plant fiber material as major ingredient, adds in plastics as a kind of emerging environment-friendly materials
Synthesis, forms a kind of extensive composite material of applicability.In the processing of wood plastic composite, since lumber fibre has very by force
Polarity, hydrophily, and plastics is nonpolar, not hydrophilic, and compatibility of the lumber fibre with plastics between the two is very poor, interfacial adhesion
Power also very little, is one very tired so by the timber with compared with strong absorptive with being combined together with hydrophobic plastics
Difficult thing can also influence the mechanical performance of wood plastic composite.Moreover, because there is very strong phase interaction between lumber fibre
With so that its dispersiveness in the plastic is very poor, to reach homodisperse more difficult.Meanwhile when being molded manufacture, wood meal
Degradable discoloration, plastics also can thermal degradation, it is unsuitable to cause the hydraulic performance decline of wood plastic composite with mixing manufacturing process.
As global resources are increasingly exhausted, social environment consciousness is increasingly surging, and timber and petroleum chemicals application are carried in production and life
Higher requirement is gone out.
Due to containing more plant fiber in Wood-plastic material, so that in the long-term use, especially in tide
Under wet environment, plastic-wood material easily causes bacterial growth because moisture is more, is scrapped so that Wood-plastic material goes mouldy, into
And improve use cost.
In addition current Wood-plastic material also has the deficiency of many aspect of performance, it is impossible to substitute timber completely, make the sector
The application in product market at home is restricted, and the plastic-wood material density such as PE, PP base material is larger, big from creepage type, is not suitable for
In applications such as external walls.The co-extruded plastic-wood product of exploitation in other nearly 2 years, as wood-plastic co-extrusion metal material, wood-plastic co-extrusion are modified
Although plastics etc. can partly solve problem above, complex production process, product high rejection rate, there are materials at two layers when in use
Remove risk.Therefore current quality and performance of the Wood-plastic material in terms of density, intensity, weatherability on the market has also needed to larger
Raising could meet the application in market.
